rusty roof tear off

I have the same situation to deal with when I get the courage up.

There's a thread on the B bdy side that's pretty good.

I understand there are 200 spot welds!

I also understand you can melt out the lead with a plumber's torch. This true?

Out of curiosity- what would be the disadvantage of culling the roof a couple inches inside the drip rails and just butt welding the new section in (assuming most of your rust issues were not directly in the drip rail area)?
